The inaugural Super Weekend is underway at the Indianapolis Motor Speedway, and Friday track visitors are in store for something new.

Thursday, crews worked all night to change from an oval track to a road course, and they'll do it again before the weekend is done. The changes were made to accommodate the Grand Am, which is a road course race.

Crews of about 50 worked all night doing the work they had weeks to accomplish when F1 was in town. This weekend brings four races: two Grand Am races Friday, the NASCAR Nationwide series Saturday, and the Brickyard on Sunday.

IMS' Doug Boles said the work is not over. After the Grand Am races, the track will have to be switched back to the oval for the Brickyard 400.

"It's a bit of a challenge. Our teams had about a year to prepare for it, and they learned a lot in the past year. What's most efficient and things to do ahead of time."

Boles also said the changes to the course are not the only ones fans will see.

"It's going to be a new experience for everybody, one we're asking our fans to understand. There will be some access for parking. Even some access for walking in the garage areas. A little restricted because there are 200-plus race cars on the ground especially around the garage areas. That said we are also adding the ability to see the cup cars in the garages like never before."

Friday's events start at 8:00 a.m. with the Grand Am Practice and Qualifying. That runs from 8:00 a.m. until 11:50 a.m.
